@Aano78 ok thanks

P.S. if you want the plane that is breaking away to be releasing flares, remove the counter measure dispensers from the copies.

You can try making a copy that has the control surfaces edited so that no inputs can affect them except trim, and place it in the same build area as the OG build, in the location you want it to be in formation (probably on front of and to the side of the OG build). Then copy it again and place it also in formation. From there, spawn in the air, go full throttle and trim out so the formation levels off, and when you go to break away using pitch and roll, only one plane should move. Then, you can get the screenshot.
